FIELD: treatment plants.
SUBSTANCE: group of invention pertains to the device for control of liquid medium, running water control and operational method of the present device. Liquid medium controlling device consists of a unit for its coupling to the mains or to the net, test chamber and pressure sensitive element. Pressure sensitive element is made capable of measuring pressure of the liquid medium. Device includes a liquid medium control unit measuring parametres of the liquid medium in the test chamber, and output valve. Output valve makes it possible to eliminate liquid medium from the test chamber. Volume of the eliminated liquid medium is set so, that liquid medium in the test chamber is replaced with the new volume of liquid medium. Device has an output control. Output control unit is capable of controlling output valve and detecting volume of the eliminated liquid medium volume, and capable of using measured pressure comparing with addition from the reference table for determination of the duration of switch on position of the output valve.
EFFECT: labor saving, improved quality of liquid medium control.
